Please find in the following table the estimated number of properties at the risk of flooding from rivers and the sea by Environment Agency Region.
Environment Agency Region 2004 2005 2006 Anglian Region 307,400 314,200 317,600 Midlands Region 214,300 222,300 222,400 North East Region 289,200 301,600 298,100 North West Region 204,600 210,000 210,900 South West Region 160,600 168,700 169,100 Southern Region 169,200 174,900 175,300 Thames Region 711,800 734,925 736,200 Environment Agency Wales 171,500 177,163 176,700 Total 2,228,600 2,303,788 2,306,300
The Environment Agency and DEFRA did not record properties by region before 2004.
The difference in the estimated number of properties at risk of flooding each year is mainly due to the improvements and refinements of the data and the modelling techniques used by the Environment Agency for the National Flood Risk Assessment.
